Afstill further object'of'the'present invention is ythe provision-of'a'reservoir'for supplying a constant flow of Water into the boiler under pres- Sure;

A- sti-lly furthenobject of thepresentiinvention isthe provision oran auxiliaryV watersupplying meansvinto the boiler for-converting the same into steam'before the means -ofgfeedingfwaterin the boilerfrom the reservoir andA conversion thereof into steam becomeoperative.`

With the abovev general objectsr'in-i Viewand others that will appear vas the inventionfis better understood, 'the -sameconsists inthe novelconstruction, combinationandarrangement of parts hereinafter more' fully describedand illustrated in the accompanying drawings and pointed outin the Vappended Claims.

In the drawings forming-a; part of this applica'- tion, and in which like designating characters refer to corresponding parts throughout the'several views:

Fig. 1 is atransverse cross-sectional view through the boiler;

Fig. 2is an elevational'diagrammatic View, on a reduced scale, of the boiler, a radiator and a waterreservoir, together with an auxiliary means for supplying water into the boiler before pressure has been generated'in the reservoir for passing water therefrom into the boiler;

Fig. 3' is a cross-sectional view on a horizontal plane, on an enlarged scale, on line 3-3 of Fig. 1; and

Fig. 4 is an enlargedcross-sectional View through the seal and locking means between the boiler proper and its closure.

Referring in detail to the present drawings there is shown therein a fire box I having its side walls downwardly tapering, and having an integrally formed and inwardly projecting ledge II for the purpose of 'supporting grate I2. Grate l2" is adaptedto receivea supply offuel upon which the same is adapted to burn, while the fire box; below grate I2 constitutes an ash comparte ment; Access into there. generatingfcompartment and ash compartment'of fire boxfI is provided'through doors (not shown) madein the endwall of said fire box I 0f Integrallyf formed withl the uppern end vof side walls ofiire box anolinwardly projecting therefrom is'flange I3 upon which the boiler restsas will be later apparent.I

Boiler |4'includes a pair oftroughs I5 in a longitudinal relation-with the boiler, and each of saidftroughs has a side wall I 6- and an inner wall I'I. The latter two are con-tinuous on transverse cross-section through the boiler',v and -form anupwardl'yl extending inverted U-shaped bulge I8.

The-lower portions of outer walls l5 of said troughs I5 are downwardly tapering and spaced from the adjacent Ytapering sidewalls ofre box Iwhile the upper portionsthereof are vertically disposed,- as is clearly seen in Fig. 1.

Aflxed to saidv upper vertical portion of the side walls I-Eir are angle ironsA I9-which, in the operative relation-of the boiler with fire box, rest upon said flange I3, thereby-supporting the :boiler in an elevated positionabove-'grate I2.

Cooperatingrwith'saidboiler I4 is a top closure 20, in'cludingfroofy 2| and integrally formed side wall 22.

Vertical wall 22fofsaid closure 2B is-removed from the `vertical portions of walls I6, so that in the-operative association of closure 2li-with boiler` Irsaid wall' 22 extends laterally and in a spaced` relation with the sidewalls of said boiler I4, as is clearly seen in Fig. 1. Exteriorlyot side Wall'of boiler I4 and downwardly depending from theupperfedge thereof is an integrally formed continuous gutter 23,' which receives quantity of cement. or other suitable sealingV material 25 within-which the lower edgev of-side wall 22 of closure 20 .is embedded, thereby forming an imperviousfseal .therebetween and said boiler I4.

Below said gutter 23*` the side wall of boilery i4 has a continuous anglev iron 25 aiiixed thereto and sidewall 22 of closurerZhas a similar angle iron.2S, thelatter disposed above the edge of said -wall 22'; A-plurality of bolts 21 are extended through the horizontal portions of said angle irons 25 and 26 in a spaced relation, the upper ends' of said; boltsreceiving in e. threaded engagement nuts 21. Saidangle irons 25 and 26 and bolts 21 constitute a clamping means between boiler IlI.v and closure 20 andmaintain thevedge of sidewall 22rmly embedded in cement 2li, and thereby 'impervious seal is established and maintained between said boiler I4` and closure 2U,A preventing` escape of. steam between'said boiler I 4 and fclosure 20.

Through pipes 28 each trough I5is adapted to receive a supply of water 29V thereto, said pipes 28fconnecting through the end wall 3Il1of boiler I4. Set within each trough I at a predetermined level of water is sealing plate 3|. Set in each sealing plate 3| is a pair of upright pipes 32 having their lower ends open and extended through said sealing plates 3l and set adjacent the bottoms of said troughs I5. The upper ends of each pair of said pipes 32 connect with horizontal pipe 33, each of which is disposed above each trough I5 and in a longitudinal relation therewith and above the plane running through the upper termination of bulge I3. These two horizontal pipes 33 have a lead pipe 34 connected thereto and centrally thereof which in turn by their opposite ends connect to a joint 35 to which in turn a horizontal perforated pipe 36 connects, Said pipe 35 is disposed above said bulge I8 and in a longitudinal relation therewith.

Water within troughs I5 will rise in pipes 32,V

and therefrom will pass into pipes 33 and 34 and into the perforated pipe 33 by means which will be later apparent. From the latter pipe water will spill through perforations in said pipe 36 upon the roof of bulge I3. By virtue of extreme heat generated below said bulge I8 any spilled water thereon will convert itself into steam. Any unconverted water will be partially retained by wings 3l provided laterally of bulge I8 and coextensively thereof until eventually the water retained by said wings 3l will either pass through perforations 3D, evaporate or any excess will spill itself over said wings and upon seal plates 3l from which it will eventually evaporate.

Referring to Fig. 2 there is shown a sealed reservoir 38 which is adapted to receive quantity of water from city water pipe. Connected with the lower end of said reservoir 38 is pipe 39 with which said pipes 28 connect, thereby supplying constantly water into troughs I5.

Connecting with the interior of the boiler and through closure 28 thereof is steam pipe 40 leading into the radiator 4i in a dwelling. Steam in said radiator 4I condenses, and the condensed water is led by return pipe 42, the latter connecting with said pipe 39 to again circulate with water passing through said pipe from reservoir 38 and into troughs I5. If any steam should pass through return pipe 42 into pipe 33 the same will be condensed in pipe 39.

Connected with boiler I4 and above the level of sealing plates 3l is pipe 43 which connects with the upper end of reservoir 38, permitting steam to pass into said reservoir 38 and into the upper end thereof so as to generate an amount of pressure within said reservoir 38, A pump P, schematically shown is connected in pipe 33 to force water under pressure into troughs I5 through pipes 28. Return pipe 42 should have a check valve 8i! provided Within it so that no water may enter thereinto from said reservoir 38.

From the hereinabove description it will be apparent that water 29 within troughs I5 is converted into steam by being spilled upon the roof of bulge I8 and from perforations in'pipe 36. This process will be operative only when water is fed into troughs I5 from reservoir 38 under boiler and pump pressure, as otherwise it could not rise through pipes 32 to spill upon bulge I8 from pipe 35. After fire in fire box I0 has been made, it will require some time before the boiler will be heated sufciently to convert water therein into steam and to generate pressure in reservoir 38 by supplying steam thereinto through pipe 43. In the interim no water would continually spill upon bulge I8, unless an auxiliary water supplying means upon bulge I8 is provided. That means includes pipe 44 which is connected by one of its ends with the bottom of reservoir 38. The opposite end thereof connects with a rubber ball 45 and has a one-way valve 46 intermediately of its two ends. Said ball 45 is in turn connected with a vertical pipe 4l which is connected through the vertical wall of the boiler with one end of perforated pipe 36.

A small-powered electric motor 48 rotates cam 49 by means of belt 53. Oi-centrically pivoted to said cam 49 is arm 5I, which by the Opposite end is connected with a lever 52- fulcrumed at 53 upon support 54. The opposite end of said lever 52 connects with arm 55. By means of said arm 5I oscillating movement to lever 52 will be imparted for intermittently actuating arm 55 in a substantially vertical direction for the purpose of intermittently pressing upon ball 45 for the purpose of ejecting water therefrom supplied from pipe 44 into pipe 4l and from the latter into pipe 35 so that the same may spill through perforations in the latter pipe. When sufficient amount of steam in boiler I4, and the consequent suicient degree of pressure in reservoir 33 has been generated, pump P is actuated to assure a constant supply of water to bulge I8 through pipe 36 and from troughs l5, the supply of water into ball 45 and pipe 4l may thereupon be disconnected by closing valve 4B and stopping the operation of motor 43.

The entire boiler I4, closure 2U, sealing connection therebetween, as well as fire box I0 may all be enclosed within an impervious and heat retaining cover 55. Gauge 5l for indicating the degree of steam pressure within boiler I4 and safety valve 58 for permitting escape of steam over a certain degree of pressure within boiler, are connected to roof 2| of closure 23, and of course should extend through cover 55.

For the sake of clearness nre box I!) as well as cover 56 have been eliminated from Fig. 2.

One end of pipe 36 may be capped as ai; 51.

Flue 59 connecting with one of the end walls 3l) of nre box I3, and below the perimeter of bulge I8, permits the escape of smoke and combustion gases into the chimney.

Optionally wings 3l' may be provided with minute perforations 6U, permitting draining of water therethrough and upon lateral faces of bulge I8, and below said wings 3l. Any excess of water will spill over the upper edges of said Wings 3l.

Independently of the boiling of water in troughs I5 and below sealing plates 3l, the water will rise through pipe 32 into the perforated pipe 35 by virtue of the supply of water under pressure through pipes 28 into said troughs l5 from said reservoir 38.

From the hereinabove description it will be apparent that lwalls of troughs I5 in conjunction with sealing plates 3l dene hermetically sealed compartments into which a constant supply of water is fed under pressure, and in which water is preheated before the same is forced to rise through pipes 32 into perforated pipe 33.

Since water below sealing plates 3i will not normally rise through pipes 32 in perforated pipes 36 until an amount of steam has been generated in the boiler so as to create pressure within reservoir 38 through pipe 43, and pump is made operative, the auxiliary water feeding means into perforated pipe 33, including motor 48, ball 45 and pipe 44, is resorted to. This auxiliary means of course is rendered inoperative by 5 disconnecting the operation of motor 48, as soon s as sufficient steam has been passed into reservoir 38 from boiler I4 through pipe 43.

Valve 46 is alternately opened and closed during the operation of the auxiliary water pumping means into pipe 4l for forcing water into perforated pipe 36. When said auxiliary water pumping means has performed its function motor 48 is then stopped and valve 46 is held in its closed position.

Check valve 6| is provided in pipe 41 so that Water pumped into pipe 41 may not return back into ball 45 and pipe 44, but may flow into perforated pipe 36.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
